yes，sir

ts = tcpserver("127.0.0.1",4000)

ts =

tc = tcpclient("127.0.0.1",4000)

How can i send and recieve stream of data through tcpip in matlab??

Note: The server and client in same computer but different Matlab scripts.Is it possible to transmitte stream of data with in acomputer,like the system act as server and client.When i run server script it will send stream of data to the client,the client will recieve the stream of data from server.

Which MATLAB libraries i want to use ?

is there any existing MATLAB examples like this available in MathWorks?

yes，sir，may be check

run in one MATLAB env

% server
close all;clear all;clc;
t_server=tcpip('0.0.0.0',4000,'NetworkRole','server');
fopen(t_server);
try_times=100;
for i=1:try_times
    pause(0.02);
    try
        data_recv=fread(t_server,t_server.BytesAvailable);
        fprintf('\n%s\n',char(data_recv));
    catch
        t_server.ValuesReceived;
    end
end

run in another MATLAB env

% client
close all;clear all;clc;
t_client=tcpip('localhost',4000,'NetworkRole','client');
fopen(t_client);
% data_send=sin(1:64);
txt_send='HELLO, Deepu S S'; 
pause(1);
% fwrite(t_client,data_send);
fprintf(t_client,txt_send);
